Hi Stefan, you wrote the Linux guest nic is defined in the directory
NICDEF 9000 TYPE QDIO DEVICES 3 LAN SYSTEM VMT1LN01 MACID E32200 So that NIC is connected to LAN VMT1LN01 not a VSWITCH od did I miss something ? What do you mean with Yes, the NIC is connected to the LAN, the LAN is connected via VSWITCH to the OSA how have you connected the virt. LAN to the VSWITCH ? VLAN 001 is the default VLAN-ID most of the real switch put all the traffic not related to a specific VLAN-ID. With other words 0001 will work as if there no VLAN-Tagging at all.
